Study on Settlement Characteristics of Composite Foundation in Shallow Bedrock of Linking-up Road near a Harbor
摘要
Abstract
Based on the CFG pile composite foundation of a harbor linking-up road, the reinforcement mechanism of composite foundation in shallow bedrock is conducted. With ABAQUS software, the effects of the distance between CFG pile and the bedrock, the rock-socket depth and different lithologies on the bearing capacity of shallow bedrock foundation are analyzed. The results show that the bearing capacity of shallow base rock CFG pile composite foundation in contributed mainly by the piles, but the soil between piles can also bear part of the load. The smaller the distance from the bedrock, the less settlement at the top of the pile and the pile soil stress ratio increases. The greater rock-socket depth, the smaller the settlement and the pile soil stress ratio increases.关键词
